Why Is My A/C Not Cooling Upstairs?

Jun 15, 2024 | Air Conditioning | 0 comments

If your dog stopped sleeping in bed with you, don’t worry – it’s not because he doesn’t love you anymore. It’s just because your A/C isn’t cooling upstairs. Many homeowners face this common issue, especially during the hot and Ohio-humid summer months. Here are some reasons why, and some solutions.

Inadequate Insulation

Poor insulation can significantly affect your A/C’s ability to cool the upper floors. Warm air from outside can easily seep into poorly insulated areas, making it difficult for your A/C to maintain a consistent temperature. Consider upgrading your insulation in the attic and walls to improve efficiency.

Blocked Vents and Registers

Check all vents and registers upstairs to ensure they are open and unobstructed. Furniture, curtains, or other objects blocking the vents can restrict airflow, making it harder for your A/C to cool the space effectively.

Faulty Ductwork

Leaky or poorly designed ductwork can lead to uneven cooling. Air can escape through gaps or leaks in the ducts before it reaches the upstairs rooms. Inspect your ductwork for any visible issues and consider having a professional perform a thorough check.

Inadequate A/C Unit Size

If your A/C unit is too small for your home, it will struggle to cool all areas, particularly the upper floors.

Thermostat Placement

The location of your thermostat can impact cooling efficiency. If the thermostat is on the first floor, it may register a cooler temperature and shut off before the upstairs is adequately cooled. Consider installing a zoned system or relocating the thermostat.

Lack of Regular Maintenance

Regular maintenance is crucial for A/C performance. Dirty filters, clogged coils, and other maintenance issues can reduce the efficiency of your system. Ensure your A/C unit is serviced regularly to keep it running optimally.
